+	  OP-TEE is an open source project which contains a full implementation
+	  to make up a complete Trusted Execution Environment. The project has
+	  roots in a proprietary solution, initially created by ST-Ericsson and
+	  then owned and maintained by STMicroelectronics. In 2014, Linaro
+	  started working with STMicroelectronics to transform the proprietary
+	  TEE solution into an open source TEE solution instead.
